PRDM9 drives the location and rapid evolution of recombination hotspots in salmonids

This study identifies PRDM9's role in driving recombination hotspots in salmonids, showing rapid evolution and conservation of its function across vertebrates.

An approximate likelihood method reveals ancient gene flow between human, chimpanzee and gorilla

Aphid, an approximate likelihood method, quantifies gene flow and incomplete lineage sorting in primate phylogenetic conflict, revealing ancient gene flow between human, chimpanzee, and gorilla.

Co-segregation of recombinant chromatids maintains genome-wide heterozygosity in an asexual nematode

The study shows that genome-wide heterozygosity in the asexual nematode Mesorhabditis belari is maintained through directed assortment of recombinant chromatids during female meiosis.

Detection of F1 hybrids from single-genome data reveals frequent hybridization in Hymenoptera and particularly ants

The paper develops a method to detect F1 hybrids from single-genome data and applies it to arthropods, finding high hybridization rates in Hymenoptera, especially ants.

Fine-scale quantification of GC-biased gene conversion intensity in mammals.

This study quantifies GC-biased gene conversion (gBGC) intensity across mammalian species and finds it is pervasive, variable, and positively correlated with effective population size.

Haplotype divergence supports ancient asexuality in the oribatid mite Oppiella nova

The paper uses genomic and transcriptomic data to show haplotype divergence patterns in asexual and sexual mite species, supporting ancient asexuality in Oppiella nova.

First annotated draft genomes of non-marine ostracods (Ostracoda, Crustacea) with different reproductive modes

The paper presents the first annotated draft genomes of three non-marine ostracod species, providing genomic resources for evolutionary and ecological studies.

Convergent consequences of parthenogenesis on stick insect genomes

This study compares parthenogenetic and sexual stick insect species to show reduced heterozygosity, less effective selection, and no TE accumulation in parthenogens.

DILS : Demographic Inferences with Linked Selection by using ABC

DILS performs demographic inferences with linked selection using ABC on population genomic data, identifying models and loci associated with gene flow and population size changes.

How much does Ne vary among species?

The paper quantifies variation in genetic drift power among species by analyzing mutation load and DFE, finding drift varies by at least 500-fold between species.

The Multilocus Multispecies Coalescent: A Flexible New Model of Gene Family Evolution

The paper introduces a new model that integrates incomplete lineage sorting and gene duplication, transfer, and loss to better simulate and infer gene family evolution.

Is adaptation limited by mutation? A timescale dependent effect of genetic diversity on the adaptive substitution rate in animals.

The paper examines how genetic diversity affects adaptive substitution rates across species, finding a timescale-dependent relationship between mutation supply and adaptation.

Sexually dimorphic gene expression and transcriptome evolution provides mixed evidence for a fast-Z effect in Heliconius

The paper examines gene expression and molecular evolution in the Z sex chromosome of Heliconius butterflies, finding mixed evidence for a fast-Z effect.

Reconstruction of body mass evolution in the Cetartiodactyla and mammals using phylogenomic data

The paper reconstructs body mass evolution in Cetartiodactyla using phylogenomic data and finds body mass affects substitution rates and GC-content dynamics.

Lacking conservation genomics in the giant Galapagos tortoise

The paper reanalyzes NGS data to show low genetic diversity and population substructure in giant Galapagos tortoises, challenging current conservation practices based on traditional markers.

Codon usage bias in animals: disentangling the effects of natural selection, effective population size and GC-biased gene conversion

This study investigates codon usage bias in 31 non-model animal species, finding translational selection in large-Ne species and GC-biased gene conversion as a dominant force across all species.
